On the G4+ There is a trigger scope function under ECU Controls.

I would start with taking a trigger capture to see if you can find a fault there. Possibly might help with incorrect arming thersholds, reluctor polarity or maybe the sensor is missing a tooth it shouldn't

Do you have a sync pulse?

Maybe put up a screen shot of your trigger capture and will see if we can see what is wrong if you don't :)
